Q. Which of the following is not an isomer of but-1-yne?
A) But-2-yne
B) Buta-1-3-diene
C) Methyl cyclopropene
D) But-2-ene
Explanation
(d)
But-2-ene and but-1-yne do not have same molecular formula, thus are not isomers
$CH_{3} - CH = CH - CH_{3}$ $CH_{3} - CH_{2} - C \equiv CH$
But-2-ene but-1-yne
$(C_{4}H_{8})$ $(C_{4}H_{6})$
