Explanation:

This talks on the  concept of reaction of Grignard reagent with carbonyl compounds.  Carbonyl compounds (aldehydes and ketones) are extremely reactive towards the nucleophile due to their highly electrophilic nature. Carbonyl groups include a carbon which is attached to the oxygen atom which highly electronegative as compared to the carbon and hence attracts the shared pair of electrons which results in the generation of partial positive character on the carbonyl carbon.

Grignard reagents on reaction with carbonyl compounds carry out a nucleophilic addition reaction which on treatment with water gives a corresponding alcohol.

For the First reaction

The reaction of Grignard reagent with the ketone is shown on the third uploaded image :

i.e Butan-2-one reacts with methyl magnesium bromide in presence of

 to form 2-methylbutan-2-ol.

For the Second reaction

The reaction of Grignard reagent with the aldehyde is shown on the fourth uploaded image :

I.e Butyraldehyde reacts with ethyl magnesium bromide in presence of

 to form hexan-3-ol.

explanation:

  the   balanced   equation   for   reaction of   ca metal   with   o2 to   produce   cao   is as below

2 ca+ o2→ 2 cao2

  explanation

the reaction is   balanced     since the   number of atoms   in reactant side is   equal to   number of atoms   in   product side.   for   example   they   are 2   atom of   ca in   reactant   side   and   2   atoms of ca   in   the product side.

  the   process   is a   meet the   requirement   of   redox   reaction because :     calcium   is   oxidized   from   oxidation state 0   to 2+   while   oxygen   is reduced from   oxidation   state   0   to 2-
