In the molecules CH_4, NF_3, NH_4^ + and H_2 O

In the molecules CH4,NF3,NH4+\mathrm{CH}_4, \mathrm{NF}_3, \mathrm{NH}_4^{+} and H2O\mathrm{H}_2 \mathrm{O}

Options

  1. Anumber of lone pairs are same
  2. Ball have same hybridisation of centre of atom
  3. Cthe bond angles are same
  4. Dnumber of bond pairs are same

Correct answer

B. all have same hybridisation of centre of atom

Step-by-step solution

CH4;bp=4;sp3\mathrm{CH}_4 ; \mathrm{bp}=4 ; s p^3-hybridisation NF3;bp=3;lp=1;sp3\mathrm{NF}_3 ; \mathrm{bp}=3 ; l p=1 ; s p^3-hybridisation NH4+;bp=4;lp=0;sp3\mathrm{NH}_4^{+} ; \mathrm{bp}=4 ; l p=0 ; s p^3-hybridisation H2O;bp=2;lp=2;sp3\mathrm{H}_2 \mathrm{O} ; \mathrm{bp}=2 ; l p=2 ; s p^3-hybridisation Hence, all have the same slope.
