CH 1 TO 3 NUMERICAL DISCUSSION

Identify electrophilic centre in the following : (1) CH_3CH=O (2) CH_3-CN (3) CH_3 I .

Discussion OF Ex-1 & 3 OF COM

The least and most stable resonating structure respectively are: (1) CH_(2)=CH-CH-CH-C-CH_(3) (2) CH_(2)=CH-CH-CH=C-CH_(3)O^(Theta) (3) CH_(2)-CH-CH=CH-C-CH_(3) (4) CH_(2)=CH-CH=CH-C-CH_(3) (А) 1,4 (В) 2,3 (С) 4,1

1.IUPAC name of CH_3-CH_2-CH(CHO)CH(CH_3)CH_2CH_3

Hydroboration-Oxidation of CH_(3)CH=CH_(2) produces (1). CH_(3)CH_(2)CH_(2)OH (2). CH_(3)CH(OH)CH_(2) (3). CH_(3)CH(OH)CH_(2)OH (4). CH_(3)COCH_(3)

Which is not the correct representation of the pi electron transfer? 1) CH_3-CH=CH_2 2) CH_2=CH-CH_2-CH_3 3) CH_3-CH=CHCN 4) CH_3-CO-CH_2-CH=CH_2

2-methyl-2-butene will be represented as (1) CH_(3)-oversetoverset(CH_(3))(|)CH-CH_(2)CH_(3) (2) CH_(3)-undersetunderset(CH_(3))(|)C=CH-CH_(3) (3) CH_(3) - CH_(2) - undersetunderset(CH_(3))(|)C=CH_(2) (4) CH_(3)-undersetunderset(CH_(3))(|)CH-CH = CH_(2)

Convert 1 - bromobutane to CH_(3)-CH_(3)-CH_(2)-CH_(2)-overset(O)overset(||)C-CH_(3)
