JJ Thomson discovered the electron :)
Correct answer: <span>An isomer with a branched structure will require:
less energy to melt than the straight chain structure.
Reason:
</span>
The branched chain compounds have lower melting and boiling points as compared to straight chain isomers.This is due to the fact that branching makes the molecule more compact. This results in decreases in surface area of isomer. But, the intermolecular attractive forces depends on the surface area of compound. Thus, branched isomers have lower intermolecular force of interaction, as compared to straight chain isomers. Consequently, the melting/boiling points of the branched chain isomers are lower as compared to straight chain isomers.
Answer:
sometimes google goes wrong
now it is showing potassium is more reactive but actually it is Not sodium is more like salts have less sodium bcz it is harmful so thats why sodium is stored in kerosene like if u inhale sodium your nose will bleed it is reactive under water and air .
hope it helps
THE EXTRACTION OF METALS FROM THEIR RESPECTIVE ORES IS KNOWN AS METALLURGY.
THE DIFFERENT PROCESS ARE :- ROASTING, CALCINATION, FROTH FLOTATION AND MGNETIC SEPARATION.
