Compare the plug shapes, voltage and frequency in Brazil and Qatar, and find out which adapter you need before you travel.
Adapter required
Yes — coming from Brazil, you will need a travel adapter for Qatar. Brazil uses Type C/Type N plugs, and Qatar uses Type G, so the pin shapes will not fit any wall socket. The mains frequency is also different (60 Hz vs 50 Hz). This rarely matters for electronics but can affect motor-driven devices like clocks and shavers.
Frequency differs (60 Hz vs 50 Hz). Rarely an issue for most electronics, but can affect motor-driven devices like clocks and shavers.

More about plugs in Qatar
In Qatar, the standard power plug is Type G. The country runs on 240 volts at 50 Hz. That means every wall socket in Qatar is the same shape — Type G, and your plug needs to physically match the socket to fit.
