TNT, properly called trinitrotoluene, is shown in the structure below.It is best prepared bya. the reaction of benzene with chloromethane, followed by 3 successive reactions withHNO 3 in the prescence of H2SO4b. the reaction of benzene with chloromethane, followed by 3 successive reactions withHNO 2 in the prescence of H2SO4c. the reaction of benzene with excess Br 2, then bromomethane, then successive reactionswith HNO 3 in the prescence of H2SO4d. the reaction of benzene with excess chloromethane followed by successive reactions withHNO 2____ 92. A chemist is designing a new fuel using cyclohexane as a starting material. The cyclohexane is exposedto Cl 2(g) and light. The resulting substance is reacted with H2O. A dehydration reaction is thenaccomplished with H2SO 4. The resulting product is slightly soluble in polar and non-polar substances.The product is:a. c.b. d.____ 93. Ethanoic acid (vinegar) when diluted to low concentrations by water can be prepared from ethene bya. reduction with H 2, followed by reaction with a strong oxidizerb. addition of HCl, followed by reaction with H2Oc. addition of H2O followed by reaction with a strong oxidizerd. addition of Br , followed by reduction with H2 2
