The major product formed when cyclohexanecarbaldehyde reacts with PhMgBr and H₃O⁺ is:

1.		2.
3.		4.	None of these

An alkene “A” on reaction with O₃ and Zn - H₂O gives propanone and ethanal in an equimolar ratio. The addition of HCl to alkene “A” gives “B” as the major product. The structure of product “B” is:

1.		2.
3.		4.

A compound A, when reacted with PCl₅ and then with ammonia, gave B. B, when treated with bromine and caustic potash, produced C. C on treatment with NaNO₂ and HCl at $0°$C and on boiling produced ortho-cresol. Compound A is:
