secondary alcohols. It used nucleophilic Grignard reagent 1-methylbutylmagnesium Bromide, and the electrophilic carbonyl carbon of an aldehyde propanal to create 4-methyl-3-heptanol. Introduction/ Purpose In this lab we took it the addition of nucleophilic Grignard reagent 1-methylbutylmagnesium Bromide, to the electrophillic carbonyl carbon of an aldehyde propanal is described. 4-methyl-3-heptanol is produced, which was a 2 degree alcohol. Both primary alcohols and secondary alcohols can be obtained

The argument for smoking prevention among adolescents is based on the observation that, if smoking does not start during adolescence, it is unlikely ever to occur and on data indicating that the probability of cessation among adults is inversely related to age at initiation. Even infrequent experimental smoking in adolescence significantly increases the risk of adult smoking. Once smoking has begun, cessation is difficult and smoking is likely to be a long-term addiction. For example, it has been

stretches. To the right of the aromatic C-H stretches, it was appeared a shoulder-type peak at 2872.07 and 2732.33 cm-1, which proves the presence of aldehyde group. In the IR graph, a very weak peak at 3396.06 cm-1 can be found. It falls in the alcohol group range, but it is very weak. Considering the actual lab situation, it is more likely to be the water group. The NMR graph doesn’t support this specific lab result since it is from another sample. This specific NMR result indicates a successful

trend of “pregaming” and the dangers of over consuming alcohol. To “pregame”, is to drink hard alcohol before going out to a party or big social event and has lead to death of 300 college students in the US. Some students may even consume up to 22 shots of hard liquor when pregaming, which can land them in hospital for alcohol poisoning. Mr. Seaman proposes that the drinking age should be lowered to 18. Lowering the drinking age would decrease alcohol abuse in college students. As the famous quote

moonining stills. As the times progressed, the governments started levying higher and higher taxes on spirites to pay war debts and to do federal duties.

where they buy and consume their alcohol is a secret. The president of Middlebury College, John Mcardell says, “kids find ways to get around the 21 year old limit. This law has been an abysmal failure. It hasn't reduced or eliminated drinking. It has simply driven it underground, behind closed doors, into the most risky and least manageable of settings."
