Question Discussion & Solution

Pattern followed is:

Hence, “GIO” is the correct answer.

The correct answer is Gold.

• Gold is not found in the Chota Nagpur Plateau.

Key Points

• Chhota Nagpur Plateau:
  • Chotanagpur plateau represents the north-eastern projection of the Indian Peninsula.
  • Chhota Nagpur plateau has an abundance of mineral resources such as mica, bauxite, copper, limestone, iron ore and coal.

Additional Information

• Gold in India is found in Karnataka and Uttar Pradesh. 

The correct answer is Bit.

Key Points

• Bit 
  • ​A bit or binary digit is the smallest unit of measurement used to quantify computer data.
  • It contains a single binary value of 0 or 1.
  • A single bit can define a boolean value of True(1) or False(0).
  • Generally, data transfer rates are measured in bits.
•  Binary Number System
  • ​It contains two unique digits 0s and 1s.
  • It is also known as the Base 2 system.
  • The binary numbers 0 and 1 are called a bit.
  • The computer always calculates input in binary form.
  • Gottfried Wilhelm Leibniz developed the binary system

Additional Information

• Byte
  • ​A byte is a unit of digital information that most commonly consists of eight bits.
  • A byte is the number of bits used to encode a single character of text in the computer.
• Nibble 
  • ​A nibble is a four-bit aggregation or half an octet.
  • it is also known as half-byte or tetrad.
• BCD
  • ​In computing and electronic systems, binary-coded decimal is a class of binary encodings of decimal numbers where each digit is represented by a fixed number of bits.
  • It is implemented in the instruction set of machines.

The pattern repeat alternatively.

The correct answer is 1 i.e. propanal.

Concept:

IUPAC nomenclature:

• A systematic method of naming organic compounds.
• Naming is based on their structures.
• It is devised by the International Union of Pure and Applied chemistry.
• Many rules are followed while naming the compounds and it is different for different functional groups.
• The rules are known as IUPAC rules.

Explanation:

• This compound contains 3 carbon atoms, so its parent alkane is propane.
• It also contains an aldehyde group (-CHO-) group which is indicated by using 'al' as suffix or ending.
• So by replacing the last 'e' of butane with 'al', the name becomes propanal.
• Thus, the IUPAC name of the compound CH3CH2CHO is propanal.
• The common name of propanal is Propionaldehyde.
