Write the IUPAC name for the following compound. (A) CH_(3)-underset(

1.	Write the IUPAC name for the following compound. (A) CH_(3)-underset(CH_3)underset(\|)CH-CH_(2)-CH_(3) (B) H_(3)C-underset(CH_3)underset(\|)overset(CH_3)overset(\|)C-CH_(3) (ii) What are Nucleophiles and Electrophiles ? Give one example each.
Answer» Solution :(A) `overset(1)CH_(3)-underset(3)underset(\|)overset(2)CH-overset(3)CH_(2)-overset(4)CH_(3)-3` methyl butane (B) `H_(3)overset(1)C-overset(CH_3)overset(2\|)underset(CH_3)underset(\|)C-overset(3)CCH_3` -2,2- dimethyl propane (ii) Electrophiles : Electrophiles are reagents that are attrached towards negative charge or electron rich center. They are either positively CHARGED ions or electron deficient neutral meolecules. Example , `CO_(2)AlCl_(3) , BF_(3), FeCl_(3),NO,NO_(2)` etc . Nucleophiles : Nucleophiles are ragents that has high affinity for electropostive centers. They possess an ATOM has unshared pair of electrons. They are usually NEGATIVELY charged ions or electron rich neutral molecules. Example : `NH_(3),R-NH_(2)R-SH,H_(2)O, R-OH, CN, OH` etc
