Question

Anner the following equations: 1- Esplain the RMM for the Ethanol. CO2 and H:0. 2. Reaction of acetylides with alkyllulites. - Synthesis 4-Oetyne and 2-hexene from starting materials which donit contain more than I carbu. 4. Synthesh 2.2-dimethyl-J-oetyne from starting material which do not contain more than 6 carbuins.

Answer 1

1) Find the RMM for b) We c) H₂O a) ethanol, mass. for relative molecular stands Am) RM M the masses 아 the It is rum of att in the compound. atoms all chemical formu mula C. Hoo a) ethanol :- atomic mass relative element 12 Carbon (c) - Hydrogen (H) 16 (0) oxygen atom loxygen 6 hydrogen & carbon, 2 we have 46 12*2 + 1*6+16 RMM : 10

b) Wy!- have I carbon atom a 2 mu oxygen atoms 12 + 2x16 - 4 4 RMM AN c) H₂O - atom I oxygen have 2 hydrogen atoms & we 19 2*1 + 1 62 RMM : with alkyl halides. - with acetylides 2) Reaction i that takes place The reaction Au) substitution Nucleophilic are strong nucleophills and lon's Autylide substituted halides giving desplace can alkyne 12)
