Logical Group Instruction ,8085 Instruction

c) Logic, 

ANA Logical AND with Accumulator
ANI Logical AND with Accumulator Using Immediate Data
ORA Logical OR with Accumulator
OR Logical OR with Accumulator Using Immediate Data
XRA Exclusive Logical OR with Accumulator
XRI Exclusive OR Using Immediate Data

The Compare instructions compare the content of an 8-bit value with the contents of the accumulator;

CMP Compare
CPI Compare Using Immediate Data

The rotate instructions shift the contents of the accumulator one bit position to the left or right:

RLC Rotate Accumulator Left
RRC Rotate Accumulator Right
RAL Rotate Left Through Carry
RAR Rotate Right Through Carry

Complement and carry flag instructions:

CMA Complement Accumulator
CMC Complement Carry Flag
STC Set Carry Flag
