Question

find the correct statements a) electron affinity of flourine is less than chlorine b) number of lone pair of electrons at central chlorine of clf3 is 2 c) iodine absorbs radiation of violet colourand appear in yellow colour

Answer 1

1. First statement is correct beacause... Though flourine have high electronegativity its electron affinity is less beacause of its small size,any extra electron if tries to come experiences intra electronic repulsion. But chlorine having bigger size overcomes this phenomenon.
2. Second statement is correct after combining with 3 flurine chlorine will be left with 2 lone pairs
3. Third statement is also correct
