2. The longest continuous carbon chain is 6 i.e hexane.

3. The substituent group attached are:

i. Methyl, CH3.

ii. Ethyl, CH2CH3.

4. we shall name the substituents alphabetically i.e ethly will come before methyl. Therefore,

Ethyl is located at carbon 3.

Methy is located at carbon 4.

The unit conversion between rankine and kelvin is (linear, exponential, quadratic, none of the above)?
diamong [38]

Answer:

Unit conversion between Rankine and Kelvin is linear.

Unit conversion between degree Celsius and degree Fahrenheit is linear.

Explanation:

Relation between rankine and Kelvin is

R\ =\ \dfrac{9}{5}\ K

So, the plot between Rankine and Kelvin is a straight line with zero intercept and has a slope having value \dfrac{9}{5}.

Relation between degrees Celsius and degrees Fahrenheit is given by

^{\circ}C\ =\ \dfrac{5}{9}\ (^{\circ}F\ -\ 32)

So, the plot between degrees Celsius and degrees Fahrenheit is a straight line with slope \dfrac{5}{9} and negative intercept of \dfrac{160}{9}.
