Question

64. Explain why long-term storage of ethers can be dangerous. 111. What is the IUPAC name for the following compound? но. SH

please answer both parts

Answer 1

The long term storage of ethers can lead to the formation of peroxides which are explosive in nature. The formation of peroxides will enhance by exposure of ether to the light and air. Hence it is advisable that to purchase ethers in small quantities and use them as early possible to avoid any explosion in the chemical laboratory HO. 1 5 SH 5-mercapto-2-methylhexan-1-ol

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

Since in the given compound, the longest carbon chain is with 6 carbon atoms, the root word is "hex"
