Question

a) Name the compound formed when a highly reactive alkali metal reacts with a

halogen and state the type of bond formed. Show the compound formation with the help

of electron dot structure.

b) An alkali metal A gives a compound B on reacting with water and produces a gas C.

Identify A, B and C and write the chemical reaction involved with a balanced chemical

equation​

Answer 1

When the alkali metals react with the different halogens (Group 7 of the periodic table), the group of compounds formed are known as the alkali metals halides. ... All alkali metal halides are white solids. Note that all the halogenThe alkali metal 'A' is potassium (K) and on reacting with water, it forms a compound 'B' which is potassium hydroxide. This upon reacting with alumnium oxide (Al2O3) forms potassium metaluminate 'C are toxic, and so these reactions should be carried out in a fume cupboard.
