CH₃COOH

N₂

Cl⁻​

Answer 1

b) HCOOH (formic acid)

Hydrogen bond is formed by attractive force between hydrogen atom & a more electronegative atom.

When formic acid is mixed with water, it forms hydrogen bonding. H-atom of H2O bonds with COO- of HCOOH while H-atom of HCOOH bonds with OH- of H2O.
