Which of the following statement (s) is/are correct (A) NaH is non-volatile hydride (B) MgH ₂ is polymeric hydride (C) NH ₃ is an electron precise hydride (D) H ₂ O is an electron rich hydride
Options
- AA, B & D only
- BA, B & C only
- CB only
- DC & D only
Correct answer
A. A, B & D only
Step-by-step solution
NH ₃ is an electron-rich hydride as N -atom has a lone pair on it. Thus, (C) is incorrect. NaH being an ionic hydride is non-volatile. Thus, (A) is correct. MgH ₂ is a polymeric hydride due to bridging hydrogens. Thus, (B) is also correct. . H ₂ O is an electron-rich hydride due to presence of lone pairs of electrons on O -atom. Thus, (D) is correct.
