Be sure to answer all parts. photochemical chlorination of pentane gave a mixture of three isomeric monochlorides. the principal monochloride constituted 46% of the total, and remaining 54% was approximately a 1: 1 mixture of the other two isomers. write structural formulas for the major product and one of the two minor products of the monochloride isomers.

the number of protons in the nucleus of a given element. has slight luster and conducts electricity at high temperatures like metal.but like a nonmetal,boron is brittle and does not conduct electricity well at low temperatures. in graphite, carbon is a soft,brittle solid.it is reflective,ductile,or malleable.

he uptake of drugs from the intestine is often strongly influenced by diffusion. for example, consider a water-insoluble steroid for treating inflammation that is solubilized in aggregates of detergent molecules, called micelles. these micelles, aggregates of 80 soap molecules, have a molecular weight of 24,000, a diameter of 2.6 nm, and a charge of -27. the positively charge ions (counterions) in this system are na".
