Q. Which of the following compounds is 2, 2, 3-trimethyl hexane?
A) $\left( CH_{3} \right)_{3}CCH\left( CH_{3} \right)CH_{2}CH_{3}$
B) $\left( CH_{3} \right)_{3}CCH_{2}\left( CH_{3} \right)_{2}$
C) $\left( CH_{3} \right)_{2}CHCH_{2}CH_{2}C\left( CH_{3} \right)_{3}$
D) $\left( CH_{3} \right)_{3}CCH\left( CH_{3} \right)CH_{2}CH_{2}CH_{3}$
Explanation
(d)
The compounds given have following structures
[image:9_image286.emf]
Out of these the (a) and (b) contain 5 C-atoms in their longest possible chains hence, these could not be the correct options for 2, 2, 3-trimethylhexane. Out of (c) and (d), the (c) is 2, 2, 5-trimethyl hexane and (d) is 2, 3, 3-trimethyl hexane
