$CH_4$

Vedclass · Answer

(A) Lewis base is defined as a substance that can donate a lone pair of electrons. $CH_4$ (Methane) has no lone pairs of electrons on the central carbon atom,as all its valence electrons are involved in covalent bonding. Therefore,$CH_4$ cannot act as a Lewis base. $C_2H_5OH$ (Ethanol) has lone pairs on the oxygen atom,Acetone has lone pairs on the oxygen atom,and Secondary amines have a lone pair on the nitrogen atom,allowing all of them to act as Lewis bases.
