Choose the correct answer from the options given below :
The molecule containing a triple covalent bond is : ammonia, methane, water, nitrogen

Options

A. Ammonia
B. Methane
C. Water
D. Nitrogen

Answer

D

Explanation

The pyramidal structure of ammonia `(NH_3)` has three sigma bonds (three single covalent bonds). The tetrahedral structure of methane `(CH_4)` has four sigma bonds (four single covalent bonds). Water `(H_2O)` has angular structure and contains two sigma bonds (two single covalent bonds). Nitrogen `(N_2)` structure is linear and has a triple bond (one sigma bond, two pi bonds). As a result, nitrogen molecules have triple bonds.
