1.	1 g of methane diffused in 20 sec. under certain conditions. Under the same conditions sqrt(20)g of a hydrocarbon (A) diffused in 40 sec. A 10 mg of sample of (A) took up 8.40 ml of H_(2) gas measured at 0°C and 760 mm pressure: The number of n. bonds present in the compound A is/are
Answer» 2 1 3 4 Solution :`SQRT((16)/(M_A)) = 1/20 xx 40/(sqrt(20)) , M_A = 80` `10 xx 10^(-3) GM to `8.4 mol of `H_2`.
