Answer 1

Hope it helps.....:))

Answer 2

n [HOOC - C₆H₄ - COOH] + n [HO - CH₂ - CH₂ -OH]

Terephthalic acid                      Ethylene glycol

                                        =

HOOC - [ - C₆H₄ - CO - O - CH₂ - CH₂ - ] n - OH    +   n H₂O

Terylene (polyester, because of the ester linkage)

For information, Terylene polyester is mostly used for making plastic bottles and clothes.
