QNEET-2022-Ch-502: NEET 2022 Chemistry - Class 11 NEET-2022-Ch-502 Solution: The decreasing order of boiling points of the following alkanes …
The decreasing order of boiling points of the following alkanes is: (a) heptane (b) butane (c) 2-methylbutane (d) 2-methylpropane (e) hexane Choose the correct answer from the options given below
Multiple Choice Options
- A (a) > (e) > (c) > (b) > (d)
- B (a) > (c) > (e) > (d) > (b)
- C (c) > (d) > (a) > (e) > (b)
- D (a) > (e) > (b) > (c) > (d)
Step-by-Step Verified Solution
_ With increase in number of carbons in alkane, boiling point increases
_ In case of isomeric alkanes, greater is the number of branches, lesser is the boiling point.
Boiling point order : Heptan e ( a ) > Hexane ( e ) > 2 _ methylbutane ( c ) > butane ( b ) > 2 _ methylpropane ( d )
