A) \[\underline{X}\]
B) \[\Delta {{H}_{f}}(H)=218kJ/mol\]
C) \[H-H\]
D) \[52.15\]
Correct Answer: B
Solution :
\[\xleftarrow[\Pr ocess]{Wac\ker }C{{H}_{2}}=C{{H}_{2}}\] The structure of A \[{{H}_{3}}C-C\equiv C-C{{H}_{3}}\] is as \[{{H}_{3}}C-C{{H}_{2}}-C\equiv CH\] bonds made by \[{{H}_{2}}C=CH-C\equiv CH\] Lone pairs of electrons on \[HC\equiv C-C{{H}_{2}}-C\equiv CH\] \[NaOH\] No. of orbitals used by O for hybridisation \[{{104}^{o}}40\] \[{{103}^{o}}\] Hybridisation of O in \[{{107}^{o}}\] Due to repulsion between two lone pairs of electrons, its shape gets distorted. There for the bond angle in the molecule is \[{{109}^{o}}28\].You need to login to perform this action.
