Find the number of hydrogen atom(s) required to complete the covalency of all the atoms in given skeleton.

Answer:

Solution:

C–C(=O)–C≡C

valency of each carbon (C has valency = 4):

1st C: single bond → needs 3 H

2nd C (C=O): already 4 bonds → 0 H

3rd C (≡): has 3 bonds with next C + 1 bond with previous → 0 H

4th C (≡): has 3 bonds → needs 1 H

Total H = 3 + 0 + 0 + 1 = 4
