Using Phenyllithium as well as any necessary organic or inorganic reagents, suggest proficient syntheses of each of the following:a) Benzyl bromideb) 1-Bromo-1-phenylcyclohexanec) trans-2-Phenylcyclohexaned) 2-Phenyl-1,3- butadiene
A 0.2527-g sample of a mixture of Mg(OH)2 and Al(OH)3 was treated with 50.00 mL of 0.225 mol L 1 HCl(aq). The resulting solution required 13.73 mL of 0.176 mol L 1 NaOH(aq) to neutralize the excess, unreacted HCl.
The overall hydrogen burning reaction in stars can be represented as the conversion of four protons to one alpha particle. Use the data for the mass of H-1 and He-4 to calculate the energy released by this process.
A key oxidative step(s) in the B-oxidation cycle of fatty acids includes: a. addition of water to a double bond b. generation of a double bond from two adjacent -CH2 carbons
A 50.0mL sample of 0.0240 M NH3(aq) is titrated with aqueous HCl. What is the pH after the addition of 15.0mL of 0.0600 M HCl(aq) kb of NH3= 1.8x10^-5.
