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.

A metal oxide reacts chemically with water to form a base in the reaction shown below. If the temperature of the metal oxide and
Alla [95]

increase the rate of chemical change.

Explanation:

The reaction of the metal oxide with water to form a base in the presence of a spike in temperature will lead to an increase in the rate of chemical change.

Temperature change has considerable effect on reaction rates.

  • Temperature is directly proportional to the average kinetic energy of reacting particles.
  • Reaction rates varies directly with a spike in temperature.
  • It has been known that for every 10°C rise in temperature, above the room temperature, reaction rates become double or tripled.
  • Temperature increases the kinetic energy of each of the reacting particles.
  • Many of the reacting particles also acquires an energy greater than or equal to the activation energy of the reaction.
  • The frequency of ordinary collisions and effective collisions per unit time increases.
