Answer 3

Increases down the group
C, Si, Ge, Sn, Pd

Question 4

Ionization enthalpy of group 14

Answer 4

C, Si, Ge, Pb, Sn (Pb and Sn switched) due to poor shielding effect

Question 5

C>Si=Ge=Sn=Pb

Question 6

Metal and non metals of g14

Answer 6

C and Si - non metals
Ge and Sn - Metalloids
pb - metals

Question 7

Mp and Bp of G14

Answer 7

Decreases down the grp

Question 8

Density of G14

Answer 8

Increases with increase in mass

Question 9

Why is pb a strong OA and Sn strong RA

Answer 9

+2 more stable. Therefore undergoes reduction losing e from its higher os state.( Due to inert pair effect)

Sn in 2+ state is a strong RA. Because of the tendency to lose e to form +4 state

Question 10

Order of catenation of g14

Answer 10

C»>Si>Ge=Sn
Pb doesn’t show catenation
