Statement I: The boiling points of the following hydrides of group 16 elements increase in the order:$\\ H_2O < H_2S < H_2Se < H_2Te \\$Statement II: The boiling points of these hydrides increase with an increase in molar mass.$\\$Choose the most appropriate answer from the options given below:

The incorrect statement regarding chirality is:

The given compound CH=CH−CH−CH_2−CH_3 | X Is an example of____

$\newline$Given below are two statements: $\newline$Statement I: The boiling point of hydrides of Group 16 elements follow the order $\newline$H₂O > H₂Te > H₂Se > H₂S. $\newline$Statement II: On the basis of molecular mass, H₂O is expected to have a lower boiling point than the other members of the group but due to the presence of extensive H-bonding in H₂O, it has a higher boiling point. $\newline$ $\newline$In the light of the above statements, choose the correct answer from the options given below:

The products A and B obtained in the following reactions, respectively, are:$\newline {3ROH + PCl₃ → 3RCl + A} \newline {ROH + PCl₅ → RCl + HCl + B}$
