When boromobenze is monochlorinated. Two isomeric compounds (A) and (B) are obtained. Monobromination of (A) gives several isomeric products of molecular formula C_(6) H_(3)ClBr_(2) . While mononbromination of (B) yields only two isomers (C) and (D) . Compound (C) is identiacla to one of the compounds obtained from the bromination of (A) . However, (D) is totally different form any of the isomeric compounds obtained from the bromination of (A) . Give the sturctures of (A),(B),(C) and (D) , and also the structers of the four isomeric mononbrominated products of (A) . Support your answer wtih resoning.

Gaseous fuels due to their advantages over ther tupes of fuels are becoming highly popular . The advantages fo the fgaseous fuels are as follows : a. High calorigic value . b. Do not produce smoke and do not leave ash after combstion . c. They can flow through pipes and can be ignige at a moment's notic eat any place . No sp-ecial devices are required for their combustion . i. Coal gas is a good gaseous fuel as it conitains 95^5 combustible gaseous such as H_2, CH_4, CO etc , It is obtained buy destructive distillation of coal at 100^@ C . ii. Water gas is a mixture of CO and H_2 and is prepared by passing steam over incandescnt coke . The reaction is owever endothermic . iii. Producer gas , which possesses low calorific value, so prepared by passing aair over red hot coke . It contains mainly nitrogen and CO iv. Semi-water gas is a mixture of water fas and producer fas . v. oil gas , which is used in laboratries , is obtained by cracking of kerosene . It is a mixture of hydrocarbon (saturated and unsatureated ) mainly lower hudrocarons . iv. LPG , which contains C_3 and C_4 hydrocarbon of the alkane and alkene serties , suppied in cylinders for domestic uses is very populsr these days . Which one of following fuels has highest percentage of CO ?
