This ether, C4H8O, can be produced by slow distillation from an acidic solution of 1,4-butanediol, HOCH2CH2CH2CH2OH. It gives a
negative test for C-C double bonds. Propose a structure for this compound.
1 answer:
Answer:
Tetrahydrofuran
Explanation:
Since the compound tested negative for C-C double bond, it must be a cyclic ether. Cyclic ethers have the oxygen atom attached to a ring. It is important to note that in a cyclic compound, one carbon atom is only bonded to two hydrogen atoms. Hence there are four carbon atoms in the compound, eight hydrogen atoms and one oxygen atom. This corresponds to the structure of tetrahydrofuran. Its structure is shown in the image attached.

Answer: Decreasing the temperature inside the container will decrease the pressure of a gas inside a closed cubical container.
Explanation:
According to Gay-Lussac's Law : 'The pressure of the gas increases with increase in temperature of the gas when volume of the gas is kept constant'.
At constant volume, pressure of the gas will decrease on decreasing the temperature or vice versa.
Decreasing the temperature inside the container will decrease the pressure of a gas inside a closed cubical container.
