Answer: Option (d) is the correct answer.
Explanation:
An orbital is defined as the energy shell which can contain a maximum of two electrons with opposite spins.
A wave like behavior of an electron is determined by an orbital and basically an orbital acts like a mathematical function.
For example, in a p-sub shell the orbitals present are 
, 
and 
.
Therefore, we can conclude that orbitals are defined by energy level.
Answer:
Salicylic acids are clear white needle shaped crystal in room temperature and are used in pharmaceutical industries to produce analgesic.
Explanation:
- Salicylic acids are aromatic organic compound also known as monohydroxybenzoic acid which is lipophilic in nature.
- the physical properties are :
- they are colorlesss and odourless at room temperature.
- boiling point is 211°C and melting point is 315°C
- they are poorly soluble in water
- its saturated solution has pH of 2.4
- the chemical properties are:
- acytylation of hydroxy group in salicylic acid gives acytylsalicylic acid which is used as aspirin.
This means that the amino acid is neutral due to the pH equals 7
