Cyclopentadiene is an organic compound with the formula C 5 H 6. It is often abbreviated CpH because the cyclopentadienyl anion is abbreviated Cp −.. This colorless liquid has a strong and unpleasant odor.At room temperature, this cyclic diene dimerizes over the course of hours to give dicyclopentadiene via a Diels-Alder reaction.This dimer can be restored by heating to give the monomer.
Q. The correct order of decreasing acidity of the acids given below is (i) Cl3CCH=CH-CH2-COOH (ii) H3CCH=CH-CH2-COOH (iii) Cl3CCH=CH-COOH (iv) H3CCH2CH2COOH
Pharmacodynamics. Tafluprost is a novel prostaglandin analog with a high affinity for the fluoroprostaglandin (FP) receptor PGF2α. Tafluprost has an affinity for the FP receptor that is approximately 12 times higher than that of the carboxylic acid of latanoprost, but with almost no potential to bind to other receptors.

Cyclopentanone is the organic compound with the formula (CH 2) 4 CO. This cyclic ketone is a colorless volatile liquid.
Cyclopentanol is an alcohol. Flammable and/or toxic gases are generated by the combination of alcohols with alkali metals, nitrides, and strong reducing agents. They react with oxoacids and carboxylic acids to form esters plus water. Oxidizing agents convert them to aldehydes or ketones. Alcohols exhibit both weak acid and weak base behavior.

CHM112 2011/2012 0.265 g of an organic compound produced on evaporation 102 cm3 of vapour at 373 K and 775 mmHg. Percentage composition of the constituents elements are 92.24 % C and 7.76 % H. Since the mineralization process produces CO 2, H 2 O, and HCl, the initial pH value of 3.4 decreased to 3.0 at 120 min irradiation time. These conditions should favor photodesorption (vide supra) and therefore a long-term irradiation was conducted in the presence of NaHCO 3 to neutralize the acid generated.

Cyclopentanol does not react with bromine. (d) Besides KMnO4, K2Cr2O7 in acidic condition is another oxidizing agent that can be used to distinguish between cyclopentanol and cyclopentanone. Acidified K2Cr2O7 oxidizes cyclopentanol into cyclopentanone. Evidence for the reaction is the orange solution (Cr2O72-) turns green solution (Cr3+).
8.1 What Are Alcohols? 241 HOW TO 8.1 (a) First, determine the root name of the cycloalkane, and replace the sufﬁx -e with -ol. OH CH 3 the root name of a 5-carbon ring is "cyclopentane" CH 3CH 2 Cyclopentanol because it's an alcohol, the -e in cyclopentane is replaced with -ol (b) Name and number the substituents. Numbering begins at the carbon bear-Glutaric acid (Pentanedioic Acid) is a linear dicarboxylic acid. It has been prepared by oxidizing cyclopentane, cyclopentanol and cyclopentanone. Glutaric acid is a pentanedioic acid. On exposure to X-rays, glutaric acid crystals generate two stable free radicals.
