Shielding effect being attendency of the inner electrons to repel the outermost electrons, an increase in shielding effect increases atomic radius and decrease reduces the atomic radius
A resting heart rate is usually around 40 beats per minute (Thats the normal amount)
Explanation:
1. Only alcohols forms hydrogen bond between themselves and with other compounds containing an O-H, N-H, or F-H bond, such as water.
2. Alcohols up to 4 carbons are miscible in water because they have hydrogen bonded to oxygen and can form hydrogen bond with water. However, it is not possible for ethers.
3. When comparing ethers and alcohols of similar molecular weights, ethers have lower boiling point than alcohol. This is because of the presence of hydrogen bond in alcohols.
