Melting point of trans-p-anisalacetophenone (with source) and
Molar mass of trans-p-anisalacetophenone (with source) (i cant find
these two things anywhere)
Procedure: 1. Carefully measure 1.0 mL each of p-anisaldehyde and acetophenone and place them in a screw-cap testtube. 2. To this add 3.0 mL of 95% ethanol. Shake the test tube gently to achieve a homogenous mixture. 3. Add 6-7 drops of 40% sodium...

what is the theoretical yield of anisalacetophenone and
dibenzalacetone formed? thank you.
The Aldol Condensation Precautions: Acetone, ethanol and acetophenone are flammable; work in a fume hood. Sodium hydroxide is a strong base and can cause severe skin burns and eye damage. Safety goggles are required. Gloves are recommended. Purpose To carry out two Aldol condensation reactions in which no heat is needed to obtain the condensation product. The two reactions differ in the number of enolizable protons at the...

hi, please help me with number 7. thank you
EXPERIMENT SEVEN SODIUM BOROHYDRIDE REDUCTION OF ACETOPHENONE HOCH, DISCUSSION The reduction of an aldehyde or ketone with sodium borohydride is straight forward and usually affords a high yield of the alcohol. The usual procedure (and the one employed in this experiment) involves dissolving the borohydride in 95% ethanol and adding the carbonyl compound to this solution. To ensure complete reaction, an excess of sodium borohydride is used. The reaction between sodium...
