An element A belongs to 14th group and occupies period number 6. A reacts with conc. HCl to give B an acid. A is used to prepare C which is used as an antiknock in automobilies. Identify the element A and the compounds B and C write the reactions

Text Solution

Verified by Experts

1. As per the position in the periodic table, the element A is lead.
2. Lead with Conc. HCl gives B
`Pb + 4HCl to H_2 PbCL_4 + H_2 `
`therefore ` Compound B is chloroplumbic acid.
3. Compound C is tetraethyl lead.
