a. cyclopropane b. cyclopentane c. cyclohexane d. cycloheptane ANS: C 57. Learn vocabulary, terms, and more with flashcards, games, and other study tools. a. hexane b.

It's the most strained so has the highest potential energy and less stable.

Another reason we try to avoid ring strain is because it will affect the structures and the conformational function of the smaller cycloalkanes. Which of the following cycloalkanes has the largest heat of combustion per carbon atom? 1. Which of the following has the list of compounds in the correct order of decreasing density (higher density > lower density)? Which of the following cycloalkanes has the largest heat of combustion? Which of the following structures is different from the other three? Angle strain and torsional strain combine to create ring strain that affects cyclic molecules. E) Since they are all isomers, all would have the same heat of combustion. A. cyclopropane B. cyclopentane C. cyclohexane D. cycloheptane 56. 58. (scroll down for part (b)) (b) rank the four cycloalkanes in order of stability from least stable to most stable. The heat of combustion of each alcohol depends on the number of carbon and hydrogen atoms in the molecular formula of the alcohol molecule.

Look at the heat of combustion per CH2 unit. The reactivity of alkanes are very less. A. cyclopropane B. cyclopentane C. cyclohexane D. cycloheptane Which of the following cycloalkanes has the smallest heat of combustion per carbon atom? But again, why is that?

What is the correct order of heats of combustion for the following cycloalkanes?

The most stable conformation of cis-1-tert-butyl-2-methylcyclo- hexane is the one in which a. the tert-butyl group is axial and the methyl group 1s equatorial. List the compound with the lowest heat of combustion first Submit Hints My Answers Give Up Review Part . Start studying O Chem Chapter 2: Alkanes and Cycloalkanes. a. cyclopropane b. cyclopentane c. cyclohexane d. cycloheptane ANSWER: a POINTS: 1 QUESTION TYPE: Multiple Choice HAS VARIABLES: False DATE CREATED: 3/12/2015 3:24 PM DATE MODIFIED: 3/12/2015 3:24 PM 56. Rank the following substances in order of decreasing heat of combustion (maximum $\rightarrow$ minimum) The answer is 2>4>1>3. Despite their relative inertness, alkanes undergo several important reactions that are discussed in the following section. Which of the following cycloalkanes has the smallest heat of combustion per carbon atom… d. both groups are equatorial.

Which of the following cycloalkanes has the smallest heat of combustion per carbon atom? The reason we do not want ring strain and steric hindrance is because heat will be released due to an increase in energy; therefore, a lot of that energy is stored in the bonds and molecules, causing the ring to be unstable and reactive. Even strong reducing and strong oxidizing agents have less effect on alkanes. 3.

(b) Rank the four cycloalkanes in order of stability from least stable to most stable. Which of the following cycloalkanes has the largest heat of combustion? I know that cyclopropane has a higher heat of combustion per bond than cyclobutane. Combustion The combustion of carbon compounds, especially hydrocarbons, has been the most important source of heat energy for human civilizations throughout recorded history. Combustion is a reaction in which a substance is burnt in presence of oxygen. Which of the following cycloalkanes has the smallest heat of combustion per carbon atom?

Jun 22,2020 - Which of the following cycloalkanes exhibits the greatest molar heat of combustion per —CH2 — group?a)Methylcyclobutaneb)Cyclopentanec)Cyclobutaned)CyclopropaneCorrect answer is option 'D'.

if you look at the link of the incorrect answer below this. As combustion of alkane produces more amount of heat… 2-methylpentane …

Can you explain this answer? If you think about it, without having the data of the heat of combustion of each type of bond, you can't really answer this question. 2). Which of the following cycloalkanes has the largest heat of combustion per carbon atom? Which of the following compounds has 1 , 2 , 3 and 4 carbon atoms? Which of the following cycloalkanes has the largest heat of combustion per carbon atom? A. cyclopropane B. cyclobutane C. cyclopentane D. cyclohexane 55. (a) Given the following reactions and their heats of combustion, calculate the heat of combustion per CH2 for cyclopropane, cyclobutane, cyclopentane and cyclohexane. Which cycloalkane has the largest heat of combustion per CH group d. IV e.v 2. a. cyclopropane b. cyclopentane c. cyclohexane d. cycloheptane ANSWER: a POINTS: 1 QUESTION TYPE: Multiple Choice HAS VARIABLES: False DATE CREATED: 3/12/2015 3:24 PM DATE MODIFIED: 3/12/2015 3:24 PM 56.
