What is the name of this hydrocarbon?

1-Fluoro-4-nitrobenzene

Step-by-step explanation:

Step 1. Identify the substituents  on the ring,

The groups are fluoro and nitro. They have no priority as functional groups, so the base name is benzene.

Step 2. Identify their relative priorities.

F and NO₂ have no functional group priority, so we list them in alphabetical order. F has alphabetical priority over NO₂. The name becomes fluoronitrobenzene.

Step 3. Number the atoms of the ring.

The C atom bearing the F is C1. Count around the ring, and the NO₂ group is on C4.

Step 4. Name the compound.

Insert the locating numbers immediately in front of the substituents. Use hyphens to join letters to numbers.

The name becomes 1-fluoro-4-nitrobenzene.

how to make a simple air condition

because natural gas is colorless, odorless, and tasteless, distributors add mercaptan (a chemical that smells like sulfur) to give natural gas a distinct unpleasant odor (it smells like rotten eggs). they locate the types of rock that are likely to contain natural gas deposits.
