The products formed by the ozonolysis `-` hydrolysis of compound of formula `C_(5)H_(8)` are
`CH_(3)-CH_(2)-CH_(2)-COOH` and `CO_(2)`. The compound is

Options

A. pent`-1-`yne
B. pent`-2-`yen
C. pent`-1,4-`diene
D. penta`-1,3-`diene

Answer

A

Explanation

Since the compound on ozonolysis `-` hydrolysis gives `1 mol` of `CO_(2)` and butanoic acid it must be terminal alkyne pent `-1-`yne
`CH_(3)-CH_(2)-CH_(2)-=CHoverset((i)H_(2)O)underset((ii)H_(2)O)rarrCH_(3)CH_(2)-CH_(2)COOH+CO_(2)`
