Give the IUPAC names for the following ethers: (i) tert-Butylphenyl ether (ii) CH_(3)underset(OCH_(3))underset(|)(CH)CH_(2)CH_(2)CH_(3) (iii) (iv) sec-Butyl isopropyl ether (v) beta-Chloroethyl methyl ether (vi) Ethyl p-nitrophenyl ether (p-nitrophenetole) (vii) cyclohexy n-propyl ether (viii) Benzy vinyl ether (ix) Cyclopentyl t-butyl ether (x) (xi) overset(1)(CH_(3))underset(OH)underset(|)overset(2)(CH)CH_(2)CH_(2)overset(5)(CH_(2))OCH_(3) (xii) 3-Cyclohexenylisopropyl ether (xiii) (xiv) Strategy: In the IUPAC system, ethers are named as alkoxyalanes. To write the IUPAC names of the commonly named ethers, first with the structure.

(ii) `2`-METHYLPENTANE
(III) `1`-Ethoxy-`4`-methylbenzene
(iv) `overset(2)(CH_(3))-underset(CH_(3))underset(|)overset(1)(CH)-O-underset(2-(1-"Methylmethoxy")but an )underset(2-"Isopropoxybutane")(underset(1CH_(3))underset(|)overset(2)(CH)-overset(3)(CH_(2))-overset(4)(CH_(3))`
(v) `Cl overset(1)CH_(2)overset(2)CH_(2)CH_(3)` , 1-Choloro-2-methoxyethane
(vi)
(vii)
