Question

For the given reactions:
(a) `C_(x)H_(y) +(x+(y)/(4))O_(2) rarr xCO_(2)+(y)/(2)[R]`
(b) `N_(2)+3H_(2) underset(200 " atm " 500^(@)C) overset( Fe+Mo) rarr [S]_("gas")`
(c ) `P_(4) +NaOH +H_(2)O overset ("boil")rarr[T]_(gas)`
The % ratio of valence electron of central atom vs total valence shell electrons is 62.5% is [S} and 27.77% in [T] and central atom of [S] and [T] belongs to same group then what is the correct order of increasing bond angle of [R]=1, [S]=2 and [T]=3? ,brgt [If your answer is `1 lt 2 lt 3` then write 0123.]

Answer 1

Correct Answer - `0312`
`{:(SrarrNH_(3),R rarrH_(2)O, TrarrPH_(3)),(" "~107^(@)," "~104.5^(@)," "~92^(@)):}`
