【導(dǎo)讀】8．K1L1某烷烴相對分子質(zhì)量為86，如果分子中含有3個(gè)—CH3、和1個(gè)，則該烴有兩種結(jié)構(gòu)為、，該結(jié)構(gòu)的烴的一氯取代物：、，有9種。本題考查同分異構(gòu)體的書寫，運(yùn)用基元法，注意取代基的不同位置，按順序?qū)?，省得遺漏，難度不大。H3C-H2C-ClC-、H3C-ClHC-H2C-、ClH2C-H2C-H2C-、2ClC-、ClH2C-CH-，5種；-C2H5O有以下結(jié)構(gòu)：-CH2CH2OH、-CHCH3、-OCH2CH3、-CH2-O-CH3,4種，兩種基團(tuán)連接苯環(huán)的對位，故有4×5=20種；本題考查了官能團(tuán)的基本性質(zhì)及同分異構(gòu)體的書寫，滿足Cl-或-OH鄰碳有氫，就可以發(fā)生消去反應(yīng)。為了測定其分子組成，進(jìn)行如下實(shí)驗(yàn)：。①在一定溫度和壓強(qiáng)下將A氣化，其氣體的質(zhì)量是同溫、同壓下等體積氦氣質(zhì)量的38倍；②稱取，在氧氣中完全燃燒，其產(chǎn)物只有CO2和水蒸氣。將反應(yīng)后的混合氣通。過濃硫酸后體積為，濃H2SO4質(zhì)量增加。再將余下的氣體通過盛有足量Na2O2. 的干燥管后，氣體體積減少至。反應(yīng)；1molA與足量Na反應(yīng)生成1molH2。入濃硫酸后的剩余氣體中CO2的物質(zhì)的量為x，O2的物質(zhì)的量為y，C8H8On，再根據(jù)相對分子質(zhì)量求出n=3；故A分子式是C8H8O3；

　　

【正文】 ； B．不含有酚羥基，則不能與 FeCl3溶液反應(yīng)顯紫色，故 B 錯(cuò)誤； C．含有 C=C，則一定條件下能發(fā)生加聚反應(yīng)，故 C 正確； D．含有 C=C，可與溴發(fā)生加成反應(yīng)而使溴的四氯化碳溶液褪色，故 D 正確。 【思路點(diǎn)撥】 本題考查有機(jī)合成和推斷，涉及有機(jī)物分子式的確定、有機(jī)反應(yīng)類型的判斷、有機(jī)方程式的書寫、同分異構(gòu)體的推斷等。 （英文版 ） easily blame, to prevent the broken window effect. Supervise the leading cadres to play an exemplary role, take the lead in the strict implementation of the code and rule , lead to safeguard the solemnity and authority of the party discipline, ensure that the party discipline and the laws and regulations for implementation in place. Throughout the discipline in the daily supervision and management , strengthen supervision and inspection, from the thorough investigation of violations of discipline behavior. Strengthen to key areas, key departments and key projects as well as the masses reflect the concentration of the units and departments for supervision. strengthening supervision, discipline inspection and supervision of cadres to set an example for pliance with the code and rule is a man must be hexyl, blacksmith needs its own hardware. Discipline inspection ans as the executor of the party discipline, and supervisor of the defenders, for its supervision must be more strictly, discipline inspection and supervision of cadres to firmly establish the awareness of Party Constitution, sense of discipline and rules consciousness, politics loyalty, sense obey. Action speak Ji Ordinance to set an example of the regulations of the rule of law, strengthen supervision and accept the supervision of the firmness and consciousness, do ply with and . To firmly establish the discipline must first be disciplined, the supervisor will be subject to the supervision of concept, and consciously safeguard and implement party passes party, take the lead in practicing three strict real strict, so loyal, clean, play. To be good at learning, the Constitution and the code as morality, politics and brought to fruition。 to implement , do not want to, dare not, not with disciplinary ruler to supervision。 to discipline a ruler, often the control inspection, and consciously in the ideological red line to draw the row Ming Good accumulation is indeed the bottom line, so that the heart has fear, said to have quit, the line has ended. Attached: indifferent to heart, calmly to the table in our life, there are many unpredictable things will happen, some good, some bad things, we cannot control is powerless to stop, but with time, you will find in life sometimes turns out to be not good, some bad things finally turned out to be a good thing, but then we muddy however did not know, this is the life teach us things. 1, life can be plex, can also be simple.
