JEE Mains · Chemistry · STD 11 - 1. Some basic concept of chemistry
A gaseous compound of nitrogen and hydrogen contains \(12.5\%\) (by mass) of hydrogen. The density of the compound relative to hydrogen is \(16\) .The molecular formula of the compound is
- A \(NH_2\)
- B \(N_3H\)
- C \(NH_3\)
- D \(N_2H_4\)
Answer & Solution
Correct Answer
(D) \(N_2H_4\)
Step-by-step Solution
Detailed explanation
In an unknown compounds containing \(N\) and \(H\) given \(\%\) of \(H\) \(= 12.5\%\) \(\therefore \) \(\%\) of \(N\) \(= 100-12.5 = 87.5\%\) Element Percentage Atomic ratio Simple ratio \(H\) \(12.5\%\) \(\frac{12.5}{1}=12.5\) \(\frac{12.5}{6.25}=2\) \(N\) \(87.5\%\)…
