(a) A solution containing methoxide ions, CH_(3)O^(-) ions(as NaOCH_(3)), in methanol can be prepared by adding sodium hybride (NaH) to methanol (CH_(3)OH). A flammable gas is the other product. Write the acidbase reaction that takes place. (b) Write the nucleophilic substitution that takes place when CH_(3)I is added and the resulting solution is heated.

Answer» <html><body><p></p>Solution :(a) We recall from <a href="https://interviewquestions.tuteehub.com/tag/section-25668" style="font-weight:bold;" target="_blank" title="Click to know more about SECTION">SECTION</a> 3.15 that sodium hybride consists of `Na^(+)` ions and hybride ions(H ions) and that the hybride ion is a very strong base. [It is the conjugate base of `H_(2)`, a very weak acid `(pK_(a) = 35)` The acid-base reaction that <a href="https://interviewquestions.tuteehub.com/tag/takes-1238575" style="font-weight:bold;" target="_blank" title="Click to know more about TAKES">TAKES</a> place is <br/> <img src="https://doubtnut-static.s.llnwi.net/static/physics_images/MST_MSC_JMA_ORG_CHE_C06_SLV_001_S01.png" width="80%"/><br/> (b) the methoxide ion <a href="https://interviewquestions.tuteehub.com/tag/reacts-1178303" style="font-weight:bold;" target="_blank" title="Click to know more about REACTS">REACTS</a> with the alkyl hallide `(CH_(3)<a href="https://interviewquestions.tuteehub.com/tag/l-535906" style="font-weight:bold;" target="_blank" title="Click to know more about L">L</a>)` in a <a href="https://interviewquestions.tuteehub.com/tag/nucleophilic-582063" style="font-weight:bold;" target="_blank" title="Click to know more about NUCLEOPHILIC">NUCLEOPHILIC</a> substitution. <br/> <img src="https://doubtnut-static.s.llnwi.net/static/physics_images/MST_MSC_JMA_ORG_CHE_C06_SLV_001_S02.png" width="80%"/></body></html>
