Which of following represents the correct order of melting point of hydrides of group -16?
H2O >, H2S > H2Se > H2Te
H2O > H2S > H2Te > H2Se
H2O > H2Te > H2Se > H2S
H2O > H2Se > H2Te > H2S
Melting point:H2O>H2Te>H2Se>H2S(373)>(222)>(208)>(188)KIn H2O ⇒ H-bondingH2Se⇒ Decreased molecular massH2S ⇒ Very less molecular mass
