Question

No. of hydrogen atoms required to saturate 5 molecules of pentyne is​

Answer 1

4 Hydrogen atoms are required to saturate pantone molecule to pentane.

Hope it helps

Answer 2

Answer:

Explanation:

One molecule of pentyne has 8 hydrogens i.e C_5H_8C

​

H

8

​

according to the alkyne general formula C_nH_{2n-2}C

H

2n−2

​

. The hydrogenation reaction of pentyne is as follow:

HC \equiv C-CH_2-CH_2-CH_3 +2H_2 \xrightarrow{Pt/Pd} CH_3-CH_2-CH_2-CH_2-CH_3HC≡C−CH

Thus for one molecule of pentyne, we require 4 stoms of hydrogen. Thus for 5 molecules of pentyne we require 20 hydrogen atoms.
