Chemistry - Complete P-block Question with Solution | TestHub
Given below are two statements
Statement I : The C-C single bond is stronger and smaller than that of single bond
Statement II : On moving down the group in Group 14, the stability of type compound increases(where = C, Si, Ge, Sn, Pb ; = Cl, Br, I)
In the light of above statements, choose the correct answer from the options given below
Options:
Answer:
Solution:
Statement I: C-C bond energy (348 kJ/mol) is greater than Si-Si bond energy (226 kJ/mol). C-C bond length (154 pm) is smaller than Si-Si bond length (235 pm). Thus, Statement I is true.
Statement II: Moving down Group 14, the stability of the +2 oxidation state increases due to the inert pair effect. Therefore, the stability of type compounds (where M is in +2 oxidation state) increases. Thus, Statement II is true.
Both statements are true.
