(B) The reaction of Grignard reagent $(RMgX)$ with formaldehyde $(HCHO)$ followed by hydrolysis yields a primary alcohol: $RMgX + HCHO$ $\rightarrow RCH_2OMgX$ $\xrightarrow{H_3O^+} RCH_2OH + Mg(OH)X$ Reaction with other aldehydes like $CH_3CHO$ yields secondary alcohols,while reaction with ketones yields tertiary alcohols. Reaction with $CO_2$ yields carboxylic acids,and reaction with $H_2O$ yields alkanes.

Primary alcohols can be obtained from the reaction of the $RMgX$ with
