PURE COVALENT bond are not directional but covalent molecule made of diff. element are directional.
2. O in water has2 lone pair electron which repeal the bonded pair e of O-H
bond ,asa result water molecule bend but in carbon di oxide this type of lone pair absent in central atom carbon.

Answer:
(1) Covalent bonds are formed by sharing of electrons and higher electronegative elements participating in bonding attract the shared pair of electrons. Hence provide a directional character to the molecule whereas ionic bonds accompany complete transfer of electrons.
(2) In water molecule , the O atom has a lone pair so it repels the bond pairs and hence a bent structure is obtained where as in carbon dioxide C does not have a lone pair.
(3) Ethyne undergoes sp hybridization so it has a linear structure.
