  • question_answer 108)   (i) Discuss the concept of hybridisation. What are its different types in carbon atom? (ii) What is the type of hybridisation of carbon atoms marked with star?                 (a)\[\overset{*}{\mathop{C}}\,{{H}_{2}}=CH-\overset{\overset{\text{O}}{\mathop{||}}\,}{\mathop{{}^{*}C}}\,-O-H\]                 (b)\[C{{H}_{3}}-\overset{*}{\mathop{C}}\,{{H}_{2}}-OH\]                 (c)\[C{{H}_{3}}-C{{H}_{2}}-\overset{\overset{\text{O}}{\mathop{||}}\,}{\mathop{{}_{*}C}}\,-H\]                 (d)\[\overset{*}{\mathop{C}}\,{{H}_{3}}-CH=CH-C{{H}_{3}}\]                 (e) \[C{{H}_{3}}-\overset{*}{\mathop{C}}\,\equiv CH\]                

    Answer:

      (i) Hybridization in carbon atoms may be represented as :     (ii)(a) \[s{{p}^{2}},s{{p}^{2}}\]                    (b)     \[s{{p}^{3}}\] (c)\[s{{p}^{2}}\]                                                (d)     \[s{{p}^{3}}\] (e) \[sp\]
