1.	Correct IUPAC name for H_(3)C- underset(underset(C_(2)H_(5))(\|))(CH)- underset(underset(C_(2)H_(5))(\|))(CH)-CH_(3) is ……..
Answer» 2-ethyl-3-methylpentane 3, 4-dimethylhexane 2 sec-butylbutane 2, 3-dimethylbutane Solution :Given STRUCTURE is written in longest simple carbon chain is as under: `overset(1)(C )H_(3)- overset(2)(C )H_(2) - underset(underset(CH_(3))(\|))overset(3)(CH)-underset(underset(CH_(3))(\|))overset(4)(CH)-overset(5)(CH_(2))-overset(6)(CH_(3))` Two methyl SUBSTITUTES are PRESENT so it is dimethyl and their positin is on `3^(rd) and 4^(th)` carbon `THEREFORE` Name is 3, 4-dimethylhexane
