HELLO,
for Tin it is more stable in 4 state than 1 state
and for lead +2 state is more stable than +4 state
this happens because as we move down the group stability of +2>+4
and as lead is in the bottom most +2>+4
and reaction of tin with HNO3 is given below
Sn + HNO3 ---------------------> SnO2 + NO2 + H2O
reaction with NaOH 
Sn + 2NaOH + 4H2O --------------------> Na2[Sn(OH)6] + 2H2
and remember that Sn do not react with HgCl2 but SnCl2 reacts because as HgCl2 is an oxidizing agent …..hence it oxideizes Sn+2 to Sn+4
so i will give you that reaction 
SnCl2 + HgCl2 + Hg + SnCl4
and reaction of tin with alkali does not takes place because as tin is a metal
THANK YOU

The inert pair effect impact could be characterized as the propensity of the electrons in the furthest nuclear s orbital to stay unionized in mixes of post-move metals. In this manner lead being a post move metal it displays this behaviour.this is on account of the s-electrons are more bound to core and accordingly more hard to ionize. 
Response with nitric corrosive 
3Sn + 8HNO3 → 3Sn(NO3)2 + 2NO + 4H2O 
Response with sodium hydroxide 
Sn + 2NaOH + 4H2O = Na2[Sn(OH)6] +2H2 
Response with antacid 
Sn(Sn)+ 2OH-(aq) +4H2O → [Sn(OH)6]2-(aq)+2H2 
Response with mercury chloride 
SnCl2 + HgCl2 → Hg + SnCl4
