Question

Dilinude, Jr. Fall 2019 1. Please draw the condensed trichloro-3-methylpentane ural formula for 2,2,3- 2. Please draw the condensed structural formula trichlorotoluene. densed structural formula for 2,3,4- 3. Please draw the condensed structural formula for 2- methoxybutane 4. Please draw the condensed structural formula for methyl ethanoate.

Answer 1

The condensed structure of a molecule shows the symbol of every central atom and each atoms bonded to a central atom 2,2,3-trichloro-3-methylpentane CI CI 4 1 2 2,3,4-trichlorotoluene 61 (common name) toluene is common name for methyl benzene cisci СІ 2-methoxybutane ok methyl ethanoate 0 (common name) esters common name is alkyl alkanoate, alkyl name is for the carbon chain attached to oxgen atom. alkanoate name is for the carbon chain attached to carbonyl group of ester.

The IUPAC name of the any compound contains 3 parts prefix+ rootword + suffix Prefix = any substitutents rootword = longest chain containing most number of carbons if the chain contains 1 carbon = meth 2 carbon = eth 3 carbon = prop 7 carbon = hept 4 carbon = but 8 carbon = oct 5 carbon = pent 9 carbon = non 6 carbon = hex and so on Suffix = if the compound contains single bond (C-C) only then suffix 'ane double bonds (C=C) 'ene triple bonds 'yne For selecting prefix numbering, the substituents numbers has to be given in such way that the sum of the all substituents should be as less as possible. For selecting rootword chain, the chain with more number of carbons has to be selected In all the given compounds alkanes are present, hence the suffix is 'ane' in all the four compound For all the compounds, blue coloured part of the name is prefix. red coloured part of the name is rootword and pink coloured part of the name is suffix
