Web(vi) Benzaldehyde and Acetophenone (vii) Ethanal and Propanal. Q:-A 5% solution (by mass) of cane sugar in water has freezing point of 271 K. Calculate the freezing point of 5% glucose in water if freezing point of pure water is 273.15 K. Q:-How the following conversions can be carried out? WebAnswer: That’s pretty much impossible to happen on its own. If this is a synthesis problem, think of it this way. Acetophenone is C6H5-CO-CH3, and so it is accessible from Friedel … Phenylacetylene is a prototypical terminal acetylene, undergoing many reactions expected of that functional group. It undergoes semihydrogenation over Lindlar catalyst to give styrene. In the presence of base and copper(II) salts, it undergoes oxidative coupling to give diphenylbutadiyne. In the presence of metal catalysts, it undergoes oligomerization, trimerization, and even polymerization. imminent creations
