1-Octene-3-ol can be prepared from hexanal in two steps. The first step involves an actylide addition reaction to hexanal. The structure of the product formed in this step is to be given and how to convert it in to 1-octene-3-ol is also to be stated. Concept introduction: When aldehydes and ketones are treated with sodium acetylide in the presence of dilute acids addition reaction occurs. The acetylide ion adds to the carbonyl carbon of the aldehyde and H adds to the carbonyl oxygen to yield an ynol in which the alcohol group is adjacent to a carbon in triple bond. To give: The structure of the product formed in the step during the reaction between hexanal and sodium acetylide in the presence of dilute acids and further to state how it can be converted in to 1-octene-3-ol.

Question

5. A buffer consists of 0.45 M NH, and 0.25 M NH-CI (PK of NH 474) Calculate the pH of the butter. Ans: 9.52 BAS PH-9.26 +10g (10.95)) 14-4.59 PH=4.52 6. To 500 ml of the buffer on #5 a 0.20 g of sample of NaOH was added a Write the net ionic equation for the reaction which occurs b. Should the pH of the solution increase or decrease sightly? Calculate the pH of the buffer after the addition Ans: 9.54

Answer 1

Question

Definition Definition Organic compounds that have a carbonyl group, C=O, as their functional group. The carbonyl group in aldehydes is placed at the end of the molecular structure, which means the C=O is attached to one hydrogen atom and an alkyl group or a benzene ring. Just like all the other homologous series in organic chemistry, the naming of aldehydes uses the suffix “-al”. The general molecular formula is C n H 2n O.
