The correct sequence of increasing coval...

The correct sequence of increasing covalent character is represented by

A

`BeCI_(2) lt NaCI lt LiCI`

B

`NaCI lt LiCI lt BeCI_(2)`

C

`BeCI_(2) lt LiCI lt NaCI`

D

`LiCI lt NaCI lt BeCI_(2)`

Text Solution

Verified by Experts

The correct Answer is:
B
Covalent character `prop` Polarisation
Polarisation `prop` Charge of cation/anion
`prop` size of anion
`prop (1)/("size")` of cation
Charge on cation
`Na^(+), Li^(+), Be^(2+)`
size `Be^(2+) lt Li^(+) lt Na^(+)`
Covalent character `NaCI lt LiCI lt BeCI_(2)`
