Kazeer [188]

Answer:

Half life = 79.67 sec

Explanation:

Given that:

k = $8.7\times 10^{-3}\ s^{-1}$

The expression for half life is shown below as:-

$t_{1/2}=\frac{\ln2}{k}$

Where, k is rate constant

So,

$t_{1/2}=\frac{\ln2}{8.7\times 10^{-3}\ s^{-1}}$

$t_{1/2}=114.94252\ln \left(2\right)\ sec=79.67\ sec$

Half life = 79.67 sec

Explain why the following is an incorrect IUPAC name. 1,3-Dimethylbutane

Sunny_sXe [5.5K]

Answer:

a. The longest chain is chosen incorrectly.

Explanation:

Hello there!

In this case, according to the given information, it turns out possible for us to firstly draw the structural formula of the 1,3-Dimethylbutane:

$CH_3-CH_2-CH(CH3)-CH_2-CH_3$

Thus, we can see that the correct name should be 3-methylpentane since the longest chain was chosen incorrectly, as it must have five carbon atoms.

Regards!
