In Hofmann's degradation reaction, produced intermediate is carbine and alkyl and Aryl both type of group can be involved in migration process, during rearrangement.

Kindly consider the following figure

Product will form by S_N2 reaction,

Kindly consider the following figure

Among all CO³⁺ has the highest +ve charge density and CN^- is the strongest ligand among all which will give maximum CFSE.

P₄ + 3NaOH + 3H₂O ->  3NaH₂PO₂ + PH₃

(It's a disproportionation reaction)

(CH₃)₄Si is called silane, while CH₃Si (OH)₃ produced 2- dimensional silicone after the removal of water, similarity ${\left(C{H}_3\right)}_{2}Si{\left(OH\right)}_2$  produced chain form and ${\left(C{H}_3\right)}_{3}Si\left(OH\right)$  produced dimer form after releasing water molecules.
