Why `H_(2)` is more stable than `H_(2)^(+)` while `He_(2)^(+)` is more stable than `He_(2)` ?

Text Solution

Verified by Experts

Bond order of `H_(2) = 1 , H_(2)^(+) = 0.5`
`He_(2)^(+) = 1.5 , He_(2) = 0`
`therefore H_(2)` is more stable than `H_(2)^(+)` but `He_(2)^(+)` is more stable than `He_(2)`.

Consider the fallowing statement : (I) CH_3OC^(o+)H_2 is more stable that CH_3CH_2^(o+) (II) Me_3C^(o+) is more stable than CH_3CH_2C^(o+)H_2 (III) CH_2=CH-C^(o+)H_2 is more stable than CH_3CH_2C^(o+)H_2 (IV) CH_2=C^(o+)H is more stable thn CH_3C^(o+)H_2 of these statement:

I and II are correct

III and IV are correct

I,II and III are correct

All are correct
