1.	(a) Write the name and symbol of group 17 element belonging to second period. (b) Write electronic configuration of K(19) . To which group of periodic table does it belongs ? (c) What are substitution reactions ? Give one example (d) What happens when acetic acid reacts with sodium bicarbonate ? Give the chemical reaction involved. (e) Why does carbon from covalent bonds ?
Answer» SOLUTION :(a) F (b) K(19) =2,8,8,1`rArr 1^(st)` group (C) `CH_(4)+Cl_(2) overset("Sunlight")to CH_(3)CL +HCl` (d) CH_(3)COOH +NaHCO_(3) to CH_(3)COONa+H_(2)O +CO_(2)` (e) Carbon contains four ELECTRONS in its outermost shell
