Which of the following statements are true

Options

A. `F gt Cl gt Br gtI`[ decreasing order of EN ]
B. `bar(F ) gt Cbar(I) gt B bar( r) gt bar(I)` [decreasing order of heat of hydration ]
C. `MI gt MBr gt MCl gt MF` [decreasing order of MP & BP ]
D. `F gt Cl gt Br gt I` [ Reactivity decreasing order ]

Answer

A, C, D

Explanation

E.N. Order `: F gt Cl gt Br gt I`
`F_(Delta)` small size `:` I is large size
Down thegroup atomic size increase so metallic nature increase.
Non-metalic nature decrease.
So, E.N. decrease and M.P. and B.P. Increase.
`MI gt MBr gt MCl gt M.F.`
