After alpha decay (234,90) remain from it
Answer:
The ability of the molecule to pack more tightly increases the melting point.
Explanation:
In hydrocarbons of same molecular formula, melting point is determined by:
- weak intermolecular forces
- Molecular symmetry
Higher the intermolecular forces and molecular symmetry, higher will be the melting point.
Intermolecular forces in hydrocarbons decreases with branching. Moreover, branching interfere the tight packing of the molecule in the crystal. Therefore, branched hydrocarbons tend to have lower melting point.
However, in highly branched hydrocarbons molecular symmetry increases which results in tight packing of the molecule in the crystal.
So, highly tight packed molecules tend to have high melting point.
As (CH3)2CHC(CH3)3 is highly branched and has high molecular symmetry, therefore, its melting point is highest among given.
So, among the given, option c is correct.
Answer:
speed and how slidey things are
Explanation:
Carbon has the right electronic bonding pattern for supporting large chains, and thus the compounds necessary for life.
No Ag cannot react with NaOH because Ag is less reactive than Na in the reactivity series and can't displace it
