4.The anticipated productof this electrophilic aromatic substitution reaction is 4-bromoacetanilide.a)From analysis of your IR s

Lady_Fox [76]

Answer:

Part a: The IR spectrum is not sufficient due to the similar radical group presence in both product and reactants.

Part b: Mass Spectrum data is required in addition to the IR data for confirming the presence of recrystallized product.

Part c: The additional data is consistent with the expectations as the data is in support of that.

Explanation:

Part a

Acetanilide has a characteristic IR peak at around 3100-3200 cm^-1 (N-H Stretching) and 1500-1680 cm^-1 (C=O Stretching). Since a similar radical group ( $NHCOCH_3$ ) is present in the 4-bromoacetanilide, thus it is difficult to affirm the presence of the product solely on the basis of IR spectrum.

Part b

Mass Spectral data will affirm the presence of recrystallized product with certainty.

Part c

4-bromoacetanilide will have $M^+$ peak at two points (213 & 215) corresponding to the two Bromine isotopes (79 & 81).

Also parent peak at 171 ( $M^+$ =43) will be in 49:51 due to presence of Bromine atoms.

Trick to change word equation to chemical equation

Elden [556K]

Answer:

actually word equation has the names and we need to write molecular formula in chemical eqn. so I don't think there is sort of trick.You just need to memorise the molecular formula of chemicals.
