Draw all possible skeletons for a 7-C compound with(a) A 6-C chain and 1 double bond
Stolb23 [73]

The possible structures with 6-C Chain and 1 double bond i.e. the isomers are                2-methylhex-2-ene , 3-methylhex-2-ene , 4-methylhex-2-ene ,                5-methylhex-2-ene , 2-methylhex-3-ene , 3-methylhex-3-ene ,                  4-methylhex-3-ene , 5-methylhex-3-ene , 2-methylhexene ,                       3-methylhexene  , 4-methylhexene , 5-methylhexene .2-methylene hexane , 3-methylenehexane .

These all are functional group  isomers.

<h3>isomers :</h3>

same molecular formula but different physical and chemical properties .

<h3>Positional isomers :</h3>

same molecular and chemical formula but different in position of the functional group .it is a structural isomerism .

<h3>functional isomers :</h3>

same molecular formula but different functional groups attached to the main ring.

The research of astronomy during the time period of 1970 - 1990 is given below:

<u>Date</u>                                                   <u>Event</u>

1. 15 June 1974               Black Brant VC sounding rocket from White Sands.

2. 14 May 1973              Launch of Skylab, the USA's first space station

3. 26 July 1971           Launch of Apollo 15

<h3>What is Astronomy?</h3>

This refers to the branch of science that deals with celestial bodies and their relation to each other.

Hence, from information about astronomy, between the time period 1970 - 1990 as it was on the 26th of December, 1974 that the Soviet space station Salyut-4 was launched.

The event I think had the greatest impact in astronomical history during this time period was the launch of Apollo 16.
