JEE Mains · Chemistry · STD 11 - 4. Chemical bonding and molecular structure
Consider the following statements: \((A)\) \(NF _3\) molecule has a trigonal planar structure. \((B)\) Bond length of \(N _2\) is shorter than \(O _2\). \((C)\) Isoelectronic molecules or ions have identical bond order. \((D)\) Dipole moment of \(H _2 S\) is higher than that of water molecule. Choose the correct answer from the option below:
- A \((A)\) and \((D)\) are correct
- B \((C)\) and \((D)\) are correct
- C \((A)\) and \((B)\) are correct
- D \((B)\) and \((C)\) are correct
Answer & Solution
Correct Answer
(D) \((B)\) and \((C)\) are correct
Step-by-step Solution
Detailed explanation
\((A)\) \(NF _3\) has trigonal pyramidal shape. \((B)\) Bond order \(\Rightarrow N _2 > O _2\) \((D)\) Dipole moment \(H _2 O > H _2 S\) Due to Electronegativity difference.
