I'm using Ubuntu 14.04 LTS in an HP pavilion 15 laptop which has BCM43142 hybrid adapter. But when I try to put my adapter in monitor mode I get the following message :
Error for wireless request "Set Mode" (8B06) :
SET failed on device wlan0 ; Operation not supported.
I am a total beginner and don't not know much about Linux systems but I can surely say that my hardware supports monitor mode as Acrylic WiFi software in windows does it gracefully.

You are right, your hardware supports Monitor Mode and many more interesting stuff. But the driver which Broadcom has released for linux OSes do not support any of these. This is why it is possible in Windows but not on Linux. You can read more about it here.
