Answer: 4-allylanisole
Explanation: The doublets behind the 7 ppm belongs to the
para-substituted benzene ring. The three single-proton multi-plets around 5−6 ppm predicts that there has to be a single subsituted alkene group
A single plus a doublet around 3-4 ppm belongs to CH3 and CH2 Groups as they could be attached to the subsituted alkene group.
Moreover the interpretation of the NMR that there is no peak with a higher intensity for >180 ppm represents an absence of Carbonyl group.
The Predicted Number is attached from a chemical database along with their peaks information
<u>Answer:</u> The time required for the conversion of benzoyl chloride to benzoic acid is 390 seconds.
<u>Explanation:</u>
The expression for the rate law of first order kinetics is given as:
......(1)
where,
= initial mass of isotope = 100 g
N = mass of the parent isotope left after the time = 100 - 25 = 75 g
t = time taken = 26 s
k = rate constant = ?
Putting values in above equation, we get:

Now, we need to find the time when 99 % of the reaction is complete. Using equation 1 again, we get:
= initial mass of isotope = 100 g
N = mass of the parent isotope left after the time = 100 - 99 = 1 g
t = time taken = ? s
k = rate constant = 
Putting values in above equation, we get:

Time required for the conversion of benzoyl chloride to benzoic acid = 416 - 26 = 390 s
About 100,000 light years
