1.	Point out the false statements in the following: (a) Lead shows allotropy. (ii) Carbon shows sp^(3) hybridisation in both diamond and graphite. (c) Tin exists in three allotropic forms. These are white. Grey and brittle. (d) +2 oxidationstate is more common in tin than in lead. (f) Carbon has themaximum tendency to catenate among theelements of group-14. (f)Both CO_(2) and SiO_(2) are gaseous at room temperature (g) Elemental silicon does not have graphites-like structure. (h) Stannous chloride can act as an oxidising agent inreactions. (i)C Cl_(4) can act as Lewis acid.
Answer» Solution : (a) Lead is the only element in group-14 which does nto show any allotorpy. (B) Carbon shows `sp^(3)` hybridisation only in diamond. In graphite, the carbon atom sare `sp^(2)` hybridised. (d) +2 oxidation state is more COMMON in lead than in tin due to greater inert pair effect. (f) only `CO_(2)` is a gas while `SiO_(2)` is a solid. (h) Stannous chloride `(SnCl_(2))` canact as reduc ing agent in its reactions because the element tin (SN) can increase its oxidation number from +2 to +4but cannot decrease it (i) `C Cl_(4)` cannot act as Lewis acid since carbon atom has novacant orbitals to accept electrons.
