Q. What do you mean by Dative Covalent Bonds?Dative Covalent Bonds
Ans.
Sometimes both electrons in the shared pair come from one atom. This type of bond is called a dative covalent bond.
For example, in the ammonium ion (NH4+) a dative bond occurs between the hydrogen ion (H+) and nitrogen atom. Here, the nitrogen atom supplies both of the electrons of the covalent bond:
Q. What are the Physical Properties of Nitric Acid? Ans. Nitric acid (HNO 3 ) may be prepared by heating sodium nitrate with sulfuric acid: NaNO 3 + H 2 SO 4 --> HNO
Why a covalent bond is directional? The covalent bond is formed as a result of pairing of two electrons in the atomic orbitals of two atoms. The bond then should lie along the
