Answer:
methyl tert-butyl ether is produced as a product
Explanation:
- Nucleophilic substitution in solvolysis reaction of tert-butyl bromide goes through
mechanism. - Because Br is a good leaving group due to it's large size and high polarizability and methanol is an weak nucleophile.
- In the first step, tert-butyl cation is produced. In the second step, methanol attacks the carbocation and produce methyl tert-butyl ether after deprotonation.
- Reaction and structure of product has been shown below.
Answer is (2) - blue.
Thymol blue is a pH indicator which 3 colors according to the pH.
Thymol blue shows red color at below pH than 1.2 and shows yellow color at the pH between 2.8 and 8.0. For the pH above 9.6, thymol blue shows blue color.
Hence, the thymol blue has 2 pH ranges as 1.2 - 2.8 and 8.0 - 9.6.
Since, pH = 11 is above the pH = 9.6, thymol blue shows blue color.
Answer : The concentration of NaOH is, 0.336 M
Explanation:
To calculate the concentration of base, we use the equation given by neutralization reaction:

where,
are the n-factor, molarity and volume of acid which is 
are the n-factor, molarity and volume of base which is NaOH.
We are given:

Putting values in above equation, we get:


Thus, the concentration of NaOH is, 0.336 M
