(ii) Uni negative anion of caro's acid shows intramoleular H- bond
(iii) Order of bond angle `Cl_(2)OgtF_(2)O`
(iv) Order of bond angle `F_(2)ltH_(2)O`
(v) Order of bond angle As
`AsI_(3)gtAsBr_(3)gtAsCl_(3)`
(vi) `BF_(3),CH_(4),PCl_(5),SF_(6),IF_(7),XeF_(4)`
all are Non polar
(vii) p-nitophenol has les boiling point as compared to o-nitrohenol
(viii) In trisilyl amine `(SiH_(3))_(3)N,` the Si-N bond length is lesser than expected value
(ix) The Be atom in `BeCl_(2)`(s) is `sp^(3)` hybridised.

Answer

8

Explanation

Intermolar hydrogen bonding causes increases in boiling point.
