Q. The number of possible alkynes with molecular formula $C_{5}H_{8}\ is$
A) 3
B) 4
C) 5
D) 6
Explanation
(a)
$C_{5}H_{8}$ has three possible alkynes. These are
$CH_{3}CH_{2} - CH_{2}C \equiv CH,\ CH_{3}CH_{2}C \equiv C - CH_{3}$
pent-1-yne pent-2-yne
$\ \ \ \ \ \ \ \ \ \ \ \ \ \ CH_{3}$
|
$CH_{3} - CH - C \equiv CH$
3-methyl but-1-yne
