The correct order of heat of combustions of the following hydrocarbon is :
`underset(P)Pent-1-ene " " underset(Q)Pentane " " underset(R)neopentane" "underset(S)isopentane`

Order of boiling points is- underset((a))("Pentan"-1-ol), underset((b))(n-"butane"),underset((c))("Pentanal"),underset((d))("ethoxyethane")

Order of boiling points is- underset((a))("Pentan"-1-ol), underset((b))(n-"butane"),underset((c))("Pentanal"),underset((d))("ethoxyethane")

Correct order of base strength of the following is underset(I)(Et-NH_(2)) , underset(II)(Et_(2)NH) ,underset(III)(Et_(3)N) ,underset(IV)(NH_(3))

Correct order of base strength of the following is underset(I)(Et-NH_(2)) , underset(II)(Et_(2)NH) ,underset(III)(Et_(3)N) ,underset(IV)(NH_(3))

The decreasing deactivating ability of the following groups is -overset(oplus)(N) underset(P)((CH_3)_3) - underset(Q)(NO_2) - underset(R)(CF_3) - underset(S)(NH_3^(+))
