Answer 3

Electrophiles

Question 4

Elements of period 2

Answer 4

lithium, beryllium, boron, carbon, nitrogen, oxygen, fluorine and neon.

Question 5

How does acidic character work along periods?

Answer 5

Acidic character is directly proportional to the EN of elements

Question 6

How does Basicity work along period?

Answer 6

It runs parallel to Nucleophilicity.

It is inversely proportional to the EN of central atom.

Acidic character is inversely proportional to which group?

Answer 8

EDG

Question 9

How is carbocation formed from alcohol?

Answer 9

Alcohols bad leaving group is concerted into a good leaving group by protonation or lewis acid reaction or reaction with TsCl
