Assertion (A) Formaldehyde is a planar molecule.
Reason (R) It contains $\mathrm{sp}^2$ hybridised carbon atom.
Assertion (A) Compounds containing - $\mathrm{CH0}$ group are easily oxidised to corresponding carboxylic acids.
Reason (R) Carboxylic acids can be reduced to alcohols by treatment with $\mathrm{LiAlH}_4$.
