Current Question (ID: 8671)

Question:

$\text{The correct classification of }\text{H}_2\text{O}, \text{B}_2\text{H}_6, \text{ and }\text{NaH}\text{ respectively is-}$

Options:

1. {Covalent, Covalent, & Covalent.}
2. {Covalent, Covalent, & Ionic.}
3. {Covalent, Ionic, & Covalent.}
4. {Interstitial, Covalent, & Covalent.}

Solution:

$\text{Hint: A covalent bond is a chemical bond that involves the sharing of}$ $\text{electron pairs between atoms. An ionic bond is when a positively}$ $\text{charged ion forms a bond with negatively charged ions.}$ $\text{Explanation:}$ $\text{Step 1: Covalent bond is present in }\text{H}_2\text{O and B}_2\text{H}_6$ $\text{H}_2\text{O} - \text{Covalent or molecular hydride (electron rich hydride).}$ $\text{B}_2\text{H}_6 - \text{Covalent or molecular hydride (electron deficient hydride).}$ $\text{Step 2: Ionic bond is present in }\text{NaH}$ $\text{NaH} - \text{Ionic or saline hydride.}$ $\text{The most electropositive element form ionic hydride with a Hydrogen atom.}$ $\text{Hence, the correct option is 2}$
