Answer:
Neopentane (C(CH3)4) have a lower a lower boiling point than n-pentane (CH3CH2CH2CH2CH3) because of it branched chain.
Explanation:
Structural isomers are compounds that have the same molecular or chemical formula but have different arrangement of atoms in space. The connectivity of the atoms differs for this compounds but they possess the same molecular formula. An example of structural isomers are butane and methyl propane. Usually, as the number of carbon increases for alkane the number of isomers also increases.
Since Isomers are different compound they are bound to have different characteristic both in melting and boiling points. Generally, straight chained isomers have higher boiling points than branched chain isomers.
n-pentane (CH3CH2CH2CH2CH3) is a straight chained isomer while neopentane (C(CH3)4) is a branched chain isomer. Neopentane (C(CH3)4) have a lower a lower boiling point than n-pentane (CH3CH2CH2CH2CH3) because of it branched chain.
Sound waves need to travel through a medium such as solids, liquids and gases. The sound waves move through each of these mediums by vibrating the molecules in the matter. ... This enables sound to travel much faster through a solid than a gas. Sound travels about four times faster and farther in water than it does in air.
Sounds can travel at approximately 6000 metres per second in some solids and at a quarter of this speed in water. This is because the molecules of solids are more tightly packed together than in liquids and those in liquids are more tightly packed than in gases.
Organic molecule. In particular, a carbohydrate.
It is physical change because ? has changed alone not with chemicals
