Answer 1

here is your answer

1..carbon atoms achieve the inert gas electron arrangement only by sharing of electrons.therefore it forms covalent bonds. A covalent bond is formed when an atom shares a pair of electron with another atom. ... This property of carbon is the only reason behind its ability of formation of long chains.

2..carbon compounds forms covalent bonds because it is tetravalent , it can neither gain or lose electrons, so it shrares them. -carbon compounds have low melting boiling point because in betweencarbon compounds covalent bonds areformed which is weaker bond.
3...a) Here X is ethanoic acid and its molecular formula is Ch3COOH
and when ethanoic acid us warmth with methanol is presence of conc. sulphuric acid the Y with sweet fragrance is formed .the compound formed is called methyl ethanoate and molecular formula is CH3 COOCH3

b) CH3COOH + C2H5OH in precence of conc.H2SO4 gives

CH3COOC2H5 +H2O
