Three isomeric pentanols with unbranched carbon chains exist. Which of these isomers, upon dehydration at 180C, yields only 1-pentene as a product?
Tunicates are marine animals that are called "sea squirts" because when they are taken out of water, they tend to contract and expel seawater. Lepadiformine is a cytotoxic agent (toxic to cells) isolated from a marine tunicate. During a recent synthesis of lepadiformine, the investigators observed the formation of an interesting by-product (3) while treating diol 1 with a reagent similar in function to PBr3 (J. Org. Chem. 2012, 77, 3390–3400):
An oxygen containing compound shows strong Infrared radiation absorption at 1630 - 1780 cm^-1 and 3200 - 3550 cm^-1. What type of compound is it likely to be? A. An ether B. A ketone C. A carboxylic acid D. An alcohol E. An aldehyde
Shown are the H NMR spectra for 2 isomeric compounds three and four of the formula C5H10O. The IR spectrum of both have an absorption in the region of 1700 to 1730 cm-1. Provide the structure for each compound, and which hydrogen atoms give rise to the peaks in each spectrum. The peak at 7.27 ppm can be ignored, and the red numbers are integration values.
Alcohols can undergo a lot of different reaction mechanims. If the alcohol group (OH) is attaached to an aromatic core, how will the chemistry change as compared to a typical alkyl alcohol? A) The OH group will become more polarised and more nucleophilic. B) The OH group will become more susceptible to oxidation C) The OH group will become more polarised and therefore basic D) The OH group will become more polarised and therefore acidic.
