Haloalkanes and...

Specific rotation is the rotation produced by $$1$$g of material in $$1$$ml of liquid in a $$1$$ dm tube. Which of the following molecules have largest value of specific rotation? (Hint : Molecular mass increasing).

The IUPAC name of $$(CH_3)_2CH-CH_2-CH_2Br$$ is ?

Arrange the following alkyl halides in decreasing order of the rate of $$\beta$$- elimination reaction with alcoholic KOH.
$${ CH }_{ 3 }{ CH }_{ 2 }{ CH }_{ 2 }Br\quad { CH }_{ 3 }-\underset { \underset { { \displaystyle \,\,\,\,CH }_{ 3 } }{ | }  }{ CH } -{ CH }_{ 2 }Br\quad { CH }_{ 3 }-{ CH }_{ 2 }-\underset { \underset {\displaystyle Br }{ | }  }{ CH } -{ CH }_{ 3 }\quad $$

The IUPAC name of tertiary butyl chloride is ?

An alkane $$C_6H_{14}$$ gives only two monochloro derivatives on chlorination. Its possible structure is:

Identify $$X$$ and $$Y$$ in the following reaction.
$$H_ 2\underset { \underset {\displaystyle Br }{ | }  }{ C } -\underset { \underset { \displaystyle Br }{ | }  }{ CH_2}+KOH\xrightarrow [  ]{ alcohol } X\xrightarrow [  ]{ NaNH_ 2 } Y$$

$$2-$$$ Bromopentane is treated with alcoholic $$KOH$$ solution. What will be the major product formed in this reaction and what is this type of elimination called?

In halogenation of aromatic hydrocarbon, a halogen carrier is used which is generally a Lewis acid. The main function of this reagent is to generate the species :

The correct decreasing order of following alkyl halides according to the rate of $$\beta$$ - elimination reaction with alcoholic KOH will be:
(i)$${ CH }_{ 3 }-\overset { \underset { | }{ H }  }{ \underset { \underset { { CH }_{ 3 } }{ | }  }{ C }  } -{ CH }_{ 2 }Br$$
(ii) $$ CH_3-CH_2-Br$$
(iii) $$CH_3-CH_2-CH_2-Br$$
