Question
Chapter 4, Problem 4.6QAP
Interpretation Introduction
Interpretation:
The best coding scheme to convert to decimal is to be determined.
Concept introduction:
BCD to decimal conversion:
A BCD number can be converted into its decimal equivalent by grouping it into four binary bits starting from LSB towards MSB progressively rightwards and then converting each four-bit binary number into its decimal equivalent.
Binary to decimal conversion:
A decimal equivalent can be obtained from a binary number by summing over decimal place value of each digit of binary, if it is

When an unknown amine reacts with an unknown acid chloride, an amide with a molecular mass of 163 g/mol (M* = 163 m/z)
is formed. In the infrared spectrum, important absorptions appear at 1661, 750 and 690 cm. The 13C NMR and DEPT spectra
are provided. Draw the structure of the product as the resonance contributor lacking any formal charges.
