The proximate standard enthalpies of formation—–
Ms H (octane) is more negative than H (methano’)

Sol: Combustion of C8H involves more number of carbons and hycirogens compared to CI-L,O

The Boyle temperatures of three gases are–— ns: I-hydrogen, Il-oxygen, Ill-ethene
Sol: More the compressibihty factor greater is the negative deviation from ideal behaviour.

For bromoal kanes——A
ns:I and III
Sol: Statements I and III are correct

The stability order of the following carbocation isA ns:ll > Ill > I> IV
Sol: II is the most stable carbocation because positive charge is at allylic position with respect to two double bonds.
IV is the least stable carbocation as it is antiaromatic
