Question
Chapter 4, Problem 4.17CP
Interpretation Introduction
Interpretation:
The condition under which the change in enthalpy (ΔH) equals the change in internal energy (ΔU) needs to be identified
Concept Introduction:
Enthalpy (H) and internal energy (U) are both
Enthalpy refers to the heat content of the system whereas internal energy refers to the energy associated with the random disordered motion of molecules

Also calculate the amount of starting materials chlorobenzaldehyde and p-chloroacetophenone
required to prepare 400 mg of the given chalcone product 1, 3-bis(4-chlorophenyl)prop-2-en-1-one
molar mass ok 1,3-bis(4-Chlorophenyl) prop-2-en-1-one = 277.1591m01
number of moles= 0.400/277.15 = 0.00144 moles
2 x 0.00 144=0.00288 moves
arams of acetophenone = 0.00144 X 120.16 = 0.1739
0.1739x2=0.3469
grams of benzaldehyde = 0.00144X106.12=0.1539
0.1539x2 = 0.3069
Starting materials:
0.3469 Ox acetophenone,
0.3069 of benzaldehyde
