Give reasons for the following :
'Carbon-oxygen bond lengths in formic acid aer `1.23 Å` and `1.36 Å` and both carbon-oxygen bonds in sodium formate have the same value, i.e., `1.27 Å`.

Text Solution

AI Generated Solution

To understand the bond lengths in formic acid and sodium formate, we need to analyze the structures and resonance forms of both compounds. ### Step-by-Step Solution: 1. **Identify the Structures**: - Formic acid (HCOOH) has a carbon atom bonded to one hydroxyl group (-OH) and one carbonyl group (C=O). - Sodium formate (HCOO⁻ Na⁺) is the sodium salt of formic acid, where the hydrogen of the carboxylic acid is replaced by a sodium ion. ...

The binary compounds of oxygen with other elements are called oxides. They are classified depending either upon their acid-base characteristics or on the basis of oxygen content. (a) Normal oxides : These oxides which contain oxygen atom as permitted by the normal oxidation number, i.e., -2 normal oxide may be acidic, basic, amphoteric or neutral. (b) Polyoxides : The oxides which contain oxygen atoms different than those permitted by the normal oxidation number of -2 . (i) Peroxides : Two oxygen atoms are linked to each other and oxyegen has -1 oxidation number. They contain (O -O)^(2-) unit. (ii) Superoxodes : These oxides contain (O-O)^(-1) unit, i.e., each O-atom has oxidation number -1//2 . (c) Suboxides : These contain low content of oxygen than expected. (d) Mixed oxides : These oxides are made of two simpler oxides. Which of the following pairs contains amphoteric oxides ?
